SPECIFICATION forming part of Letters Patent No. 326,039, datedSeptember 8, 1885.

Application filed January 27, 1885. (No model.) i

To all whom it may concern:

Be itknown that I, EDGAR A, JONES, of Three Rivers, in the county of St.Joseph and State of Michigan,have invented certain new and usefulImprovements in Springs; andIdo hereby declare the followin g to be afull, clear, and exact description of. the invention, such as willenable othersskilled in the art to which it appertains to make and usethe same.

My invention relates to an improvement in. springs for bed-bottoms, theobject of the same being to provide adevice of this character by meansof which a'durable and efficient support lwill be afforded equably toall portions of a A further object is to provide a device of I thischaracter which shall be simple and economical in construction anddurable and efficient in use,- and with these ends in view my inventionconsists in a coil-spring adapted to connect with side and oppositespring, thus rendering an intermediate support between the slats andsprings secured thereto.

My invention further consists in the certain details of construction andcombinations of parts, as will be hereinafter described, and pointed outin the claim.-

In the accompanying drawings,Figure 1 represents a plan view of a bedbottom composed of the improved springs. Fig. 2 isa viewin sideelevation of one of the springs secured to a slat. Fig. 3 shows anenlarged view of the hooked end of the lateral extension of the springs.Figs. 4 and 5 are views of modified forms of springs.

The springs a are made of ordinary bedspring wire, and; can be of anydesired size and shape, and each is provided at its lower end with thespring-clamp b,by means of whichit is securely held in positionoon thebed-slat. The spring-clamps are made integral with the spring proper,and each is formed by bending the lower coil downward a suitabledistance and then inward, terminating in an upwardlyprojecting end, 0,which latter is situated approximately to the vertical axis of thespring. The space between the upwardly-projecting end of the clamp andthe lower coil of the spring is slightly smaller than the slat, so thatit becomes necessary when securing the springs to the slats toincreasethespace,which is done by drawing the spring-clamp downward. The

upper coil, d, of the spring is extended laterally asufficientdistanceand then turned backward, forming an acute angle or V shape. The freeend of the spring is provided with the hook g, formed at right angles tothe horizontal axis of the spring. i

The springs are attached to a bed in the following manner! One of thesprings is first secured to the head-slat h by means of the spring-clampb. The nextspringis then placed in position on the slat, the upper coil,d, thereof having been first slipped through the V-shape angle 6 in thelaterally-adjacent spring, and when secured the upper coil engages theangle, as shown at t in the drawings. After the upper row of springshave been placed in position, as described, the springs continue to besecured to the slats below, and the hooked ends 9 engage with the upperportions of the upper coils of the longitudinally-adjacent springsbelow, thus affording a secure attachment and a complete net-work ofwire over the entire surface of the bed. i

The springs attached to the foot-slat j are providedwith thelateralextension and hooked end only, thus dispensing with the V-shaped Isection, and the hooks are attached to the lat-' erally-adjacentsprings, as shown.

At one side of the bed the springs are reversed and placed on frame. Thelower edge of the slat and the V-shaped angle of the arm engages withthe upper coil of the laterally-adjacent spring in such a manner as toform a double row of arms between the slats, thus leaving the outsiderow of springs firmly secured and smooth upon their outer edge.

Another modification of this deviceforconnecting the top of thespringsis shown in Fig. 4, in which the lateral extension of the top coil ofthe spring is bent over back at the acute or V-shaped angle, at a lessdistance from the coil, is then extended back laterally far enough tomeet the elbow to the adjoining spring on the same slat, and then bentor curved and brought back about or nearly half-way, the end terminatingin the hook g, to attach to the upper coil of thelongitudinally-adjacent spring. Bythis method the place of contact withthelaterallyadjacent spring is at the point where the ends of the armsmeet, instead of directly on the upper coil of the spring.

A further slight modification is shown in IOO Fig. 5, in which thelateral extension of the top coil is cut off somewhat shorter, and thecurve in the wire near the hook g omitted, as seen in the drawings.

It will be seen that the construction described overcomes the defectheretofore experienced in the use of spiral springs, as the spacebetween the several springs is filled by the curved extensions, and thebed is thus supported at every point.

These springs can be manufactured at a small initial cost and applied toa bed with out the use of skilled labor, and are therefore speciallyadapted to be made and sold by persons of ordinary capability andlimited capital. They are simple in construction and durable andefficient in use.

I am aware that it is not broadly new to provide a bed-spring with abent arm con structed to be passed through or arou nd the top coil of aspring on the adjacent slat,and thence back to the adjacent spring onthe same slat. In this device above referred to,and in others wherein abent arm passes through the top coil of an adjacent spring, it isimpossible to adjust the springs toward or away from each other withoutturning the spring on the slat orwithout cramping or bending the armsthereof. In my device the arm of one spring engages the bent arm of theadjacent spring on the same slat. This permits the arm of one spring toslide freely on the arm of the adjacent spring;

hence I am enabled to move the springs on the same slat closer togetheror farther apart without turning the springs on the slat and withoutstraining or bending the springs or arms.

I am aware that it is also old to bend the free end of the upper coil ofaspring to formaloop 0r hook; hence I make no claim to this part,separately considered; but,

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is

A bedspring having a straight arm or extension forming a continuation ofthe upper coil thereof, the said straight arm being provided with acontinuation extending rearwardly in a diagonal direction, the latterhaving a hook-shaped end, the said straightarm adapted to rest parallelor approximately parallel with the slat and in a line, and interlockwith the straight arm of the next spring, whereby the springs can bemoved toward and away from each other without straining the springs orarms, substantially as described.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.

EDGAR A. JONES.
